SAMUEL KLAHR, OF REAMSTOVVN, PENNSYLVANIA.

BORING-MACHINE.

Specification of Letters Patent No. 16,241, dated December 16, 1856.

To all whom it may concern:

Be it known that I, SAMUEL KLAHR, of Reamstown, county of Lancaster andState of Pennsylvania, have invented an Improved Boring-Machine; and Ido hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisspecifica-tion.

The nature of my invention consists in the combination of the severaldevices for boring posts and'pump stocks which I call the improvedportable boring machine.

To enable others skilled in the art to make and use my invention I willproceed to describe'its construction and operation.

A is a square frame support-ing the devices for boring posts.

B is an extension frame, attached to frame A Which supports the devicesfor Y boring pump stocks, or any long pieces of timber, lengthwise.

C is a railway carriage resting on the top of frame A and carries theauger D.

E is a pulley on the shaft of auger D.

F is a lever attached to carriage C by which the carriage and auger Dare moved forward while boring, or at any time withdrawn from the lumberor piece bored.

Gr a horizontal and adjustable platform to which the post or piece oflumber is attached, and which is moved crosswise, the required distanceto regulate the holes apart. The platform G has teeth underneath whicharc operated on by a pinion H, which pinion H is moved by the crank I.

J is a drum on the shaft K secured to the frame A by journal boxes. Thedrum J causes the auger D to revolve by a band L passing around it andthe pulley E.

On the shaft K is a pulley M which is put in motion by a band O passingaround it and the main driving wheel P. The carriage Q (on the frame B)which carries the pump stock to the auger D is attached to an endlesschain R which passes around pulleys S and T. These pulleys are of threesizes, and the endless chain is placed over the larger or smallerpulleys according to the speed required. The pulleys T have projectingpins U which catch hold of the links or apertures of the chain R,preventits slipping, and assist in regulating its motion. The whicreceives its motion from a vertical endless screw IV on the upper end ofvertical shaft X. This vertical shaft X has a pinion Y at its lower end.An endless screw Z on the horizontal shaft K gears into the pinion Y onthe vertical X, and the endless screw IV gears into the Vpinion V andthus the pulleys T receive their motion.

I/Vhat I claim as my invention and desire to secure by Letters Patentis- 1. The arrangement and combination of the shaft X endless screw Z,pinion and pulleys T as operating on an endless chain and railwaycarriage for the purpose of boring pump stocks as described.

2. I also claim the shape and construction of the pinion V and pulleys Twith pins U, solid on one'shaft, for the purpose herein set forth.

3. I do not claim the combination and arrangement of the drum J with thedevices for operating the carriage C, but what I do claim as myinvention is the combination and arrangement of the drum J with thedevices for operating bot-h of the carriages C and Q for boring postsand pump stocks forming a neat portable boring machine substantially asherein set forth.
